Repeated hand urticaria due to contact with fishfood. (1/402)
BACKGROUND: The etiology of urticaria is often difficult to determine. However, in case of repeated circumstance-connected urticaria, the reason may be easily clarifyable. CASE: A 51-year-old healthy woman repeatedly experienced occupational hand urticaria when handling fish food. An unexpected reason for the urticaria was found in that the fishfood contained histamine as a "contaminant". CONCLUSIONS: In fishfood batches, biological degradation can produce histamine and possibly other toxic substances that can lead to occupational health problems. (+info)Genetic linkage of the Muckle-Wells syndrome to chromosome 1q44. (2/402)
The Muckle-Wells syndrome (MWS) is a hereditary inflammatory disorder characterized by acute febrile inflammatory episodes comprising abdominal pain, arthritis, and urticaria. Progressive nerve deafness develops subsequently, and, after several years, the disease is complicated by multiorgan AA-type amyloidosis (i.e., amyloidosis derived from the inflammatory serum amyloid-associated protein) (MIM 191900) with renal involvement and end-stage renal failure. The mode of inheritance is autosomal dominant, but some sporadic cases have also been described. No specific laboratory findings have been reported. The genetic basis of MWS is unknown. Using a genomewide search strategy in three families, we identified the locus responsible for MWS, at chromosome 1q44. Our results indicate that the gene is located within a 13.9-cM region between markers D1S2811 and D1S2882, with a maximum two-point LOD score of 4. 66 (recombination fraction.00) at D1S2836 when full penetrance is assumed. Further identification of the specific gene that is responsible for MWS will therefore provide the first biological element for characterizing MWS, other than doing so on the basis of its variable clinical expression. (+info)Acquired lipoprotein lipase deficiency associated with chronic urticaria. A new etiology for type I hyperlipoproteinemia. (3/402)
Type I hyperlipoproteinemia (type I HLP) is a rare disorder of lipid metabolism characterized by fasting chylomicronemia and reduced postheparin plasma lipoprotein lipase (LPL) activity. Most cases of type I HLP are due to genetic defects in the LPL gene or in its activator, the apolipoprotein CII gene. Several cases of acquired type I HLP have also been described in the course of autoimmune diseases due to the presence of circulating inhibitors of LPL. Here we report a case of type I HLP due to a transient defect of LPL activity during puberty associated with chronic idiopathic urticaria (CIU). The absence of any circulating LPL inhibitor in plasma during the disease was demonstrated. The LPL genotype showed that the patient was heterozygous for the D9N variant. This mutation, previously described, can explain only minor defects in the LPL activity. The presence of HLP just after the onset of CIU, and the elevation of the LPL activity with remission of the HLP when the patient recovered from CIU, indicate that type I HLP was caused by CIU. In summary, we report a new etiology for type I HLP - a transient decrease in LPL activity associated with CIU and with absence of circulating inhibitors. This is the first description of this association, which suggests a new mechanism for type I HLP. (+info)Inhibition of aminopeptidase P potentiates wheal response to bradykinin in angiotensin-converting enzyme inhibitor-treated humans. (4/402)
Bradykinin is a nonapeptide that contributes to the cardioprotective effects of angiotensin-converting enzyme (ACE) inhibitors. During ACE inhibition, an increased proportion of bradykinin is degraded through non-ACE pathways. Studies in animals suggest that aminopeptidase P (EC 3.4.11.9) may contribute to the metabolism of bradykinin. The purpose of the present study was to determine the contribution of aminopeptidase P to the degradation of bradykinin in humans in the presence and absence of ACE inhibition. To do this, we measured the wheal response to intradermal injection of bradykinin (0, 1, or 10 nicrog) in the presence or absence of intradermal administration of the specific aminopeptidase P inhibitor apstatin (5 or 10 microg) and oral administration of the ACE inhibitor quinapril (10 mg) in six healthy subjects. Both bradykinin (ANOVA; F = 101.18, P <.001) and apstatin alone (F = 7.01, P =.049) caused a wheal of dose-dependent size. There was no significant interaction between apstatin and bradykinin (F = 4.94, P =.175). Pretreatment with 10 mg of quinapril significantly shifted the dose-response curve for bradykinin to the left (effect of quinapril; F = 77.96, P <.001) and there was significant interaction between quinapril and bradykinin (F = 7.82, P =.041). The effect of quinapril was significantly potentiated by coinjection of 10 microg of apstatin (effect of apstatin; F = 21.60, P =.006), such that there was significant interactive effect of quinapril and apstatin (F = 20.83, P =.006) on the wheal response to bradykinin. Collectively, these data suggest that aminopeptidase P plays a minor role in the degradation of bradykinin in human skin in the absence of ACE inhibition but contributes significantly to the degradation of bradykinin in the presence of ACE inhibition. (+info)Pharmacodynamic interaction of eltanolone and alfentanil during lower abdominal surgery in female patients. (5/402)
We have studied the influence of eltanolone on intraoperative alfentanil requirements in 18 female patients undergoing lower abdominal surgery receiving target-controlled infusions of eltanolone and alfentanil. While target concentrations of eltanolone were maintained constant, target concentrations of alfentanil changed in response to the presence or absence of responses. With serum eltanolone concentrations increasing from 500 to 2000 ng ml-1, the EC50 of alfentanil for suppression of responses to surgical stimulation decreased from 233 to 9 ng ml-1. The findings suggest that the interaction between eltanolone and alfentanil is synergistic. (+info)Additive-induced urticaria: experience with monosodium glutamate (MSG). (6/402)
In patients with chronic urticaria, the incidence of reactions to any additives, including monosodium glutamate (MSG), is unknown. Although many studies have investigated the association of additives and urticaria, most have been poorly designed. This study sought to determine the prevalence of reactions to additives, including MSG, in patients with chronic urticaria using a rigorous protocol. We studied 65 subjects (44 women, 21 men; ages 14-67). All had urticaria for >6 wk without discernible etiology. Subjects with active urticaria were studied while they were taking the lowest effective dose of antihistamine. Screening challenges to the 11 additives most commonly associated with exacerbations of chronic idiopathic urticaria were performed in a single-blind fashion. The dose of MSG given was 2500 mg. Skin scores were obtained to determine a positive reaction in an objective manner. Subjects with a positive screening challenge were rechallenged (at least 2 wk later) with a double-blind, placebo-controlled protocol as in-patients in our General Clinical Research Center. Two subjects had positive single-blind, placebo-controlled challenges, but neither had a positive double-blind, placebo-controlled challenge. We conclude, with 95% confidence, that MSG is an unusual (<3% at most) exacerbant of chronic idiopathic urticaria. (+info)Identification of a locus on chromosome 1q44 for familial cold urticaria. (7/402)
Familial cold urticaria (FCU) is a rare autosomal dominant inflammatory disorder characterized by intermittent episodes of rash with fever, arthralgias, conjunctivitis, and leukocytosis. These symptoms develop after generalized exposure to cold. Some individuals with FCU also develop late-onset reactive renal amyloidosis, which is consistent with Muckle-Wells syndrome. By analyzing individuals with FCU from five families, we identified linkage to chromosome 1q44. Two-point linkage analysis revealed a maximum LOD score (Zmax) of 8.13 (recombination fraction 0) for marker D1S2836; multipoint linkage analysis identified a Zmax of 10. 92 in the same region; and haplotype analysis defined a 10.5-cM region between markers D1S423 and D1S2682. Muckle-Wells syndrome was recently linked to chromosome 1q44, which suggests that the two disorders may be linked to the same locus. (+info)Medical surveillance of allergy in laboratory animal handlers. (8/402)
Allergic disease is a serious occupational health concern for individuals who have contact with laboratory animals. The principal respiratory symptoms include allergic rhinitis, conjunctivitis, and asthma. Urticaria (" hives") is the most common skin manifestation. The overall prevalence of allergic disease among laboratory animal handlers is about 23%, and respiratory allergy is much more common than skin allergy. Various studies have found annual incidence rates ranging from 2% to 12%. Prevention of animal allergy depends on control of allergenic material in the work environment. Personal protective equipment such as air filtering respirators should be used in addition to the other exposure control technologies where conditions require. Pre-placement evaluation and periodic medical surveillance of workers are important pieces of the overall occupational health program. The emphasis of these medical evaluations should be on counseling and early disease detection. The article gives recommendations for the content of the medical evaluations. (+info)Urticaria, also known as hives, is an allergic reaction that appears on the skin. It is characterized by the rapid appearance of swollen, pale red bumps or plaques (wheals) on the skin, which are often accompanied by itching, stinging, or burning sensations. These wheals can vary in size and shape, and they may change location and appear in different places over a period of hours or days. Urticaria is usually caused by an allergic reaction to food, medication, or other substances, but it can also be triggered by physical factors such as heat, cold, pressure, or exercise. The condition is generally harmless, but severe cases of urticaria may indicate a more serious underlying medical issue and should be evaluated by a healthcare professional.
Urticaria pigmentosa is a rare mast cell disorder, characterized by the development of brownish-red, raised lesions (maculopapules) on the skin. These lesions are often found on the trunk and proximal extremities, but can occur anywhere on the body. They are typically asymptomatic, but may become itchy or even painful when subjected to friction, heat, or emotional stress. In some cases, these lesions may also release histamine, leading to symptoms such as flushing, headache, and hypotension. Urticaria pigmentosa is more common in children than adults, and typically resolves on its own over time. However, in some cases it can persist into adulthood or even progress to systemic mastocytosis, a more severe form of the disorder that can affect internal organs.
Angioedema is a medical condition characterized by rapid swelling of the skin, mucous membranes, and submucosal tissues. The swelling typically occurs in the face, lips, tongue, larynx, and extremities, and can also affect the gastrointestinal tract. Angioedema can be caused by a variety of factors, including allergic reactions, hereditary genetic mutations, and certain medications.
In medical terms, angioedema is defined as a self-limiting episode of localized edema in the deep dermis, subcutaneous tissue, or mucous membranes, characterized by well-circumscribed, nonpitting, nondependent swelling. The swelling can occur suddenly and may persist for up to 72 hours. In severe cases, angioedema can cause airway obstruction and be life-threatening if not treated promptly.
Angioedema can be classified into two main types: allergic or non-allergic. Allergic angioedema is caused by an immune response to an allergen, such as food, medication, or insect venom. Non-allergic angioedema can be further divided into several subtypes, including hereditary angioedema (HA), acquired angioedema (AAE), and drug-induced angioedema.
Hereditary angioedema is a rare genetic disorder caused by mutations in the C1 inhibitor gene, leading to uncontrolled activation of the complement system and increased production of bradykinin, a potent vasodilator. Acquired angioedema is similar to hereditary angioedema but occurs later in life and is associated with underlying medical conditions such as lymphoproliferative disorders or autoimmune diseases. Drug-induced angioedema can be caused by a variety of medications, including ACE inhibitors, angiotensin receptor blockers (ARBs), and nonsteroidal anti-inflammatory drugs (NSAIDs).
The diagnosis of angioedema is typically based on clinical presentation, medical history, and laboratory tests. Treatment depends on the underlying cause of the condition but may include antihistamines, corticosteroids, epinephrine, and medications that target the complement system or bradykinin pathway. In severe cases, hospitalization and intensive care may be necessary to manage airway obstruction and other complications.
Histamine H1 antagonists, non-sedating, also known as second-generation antihistamines, are medications that block the action of histamine at the H1 receptor without causing significant sedation. Histamine is a chemical mediator released by mast cells and basophils in response to an allergen, leading to allergic symptoms such as itching, sneezing, runny nose, and hives.
The non-sedating antihistamines have a higher affinity for the H1 receptor and are less lipophilic than first-generation antihistamines, which results in less penetration of the blood-brain barrier and reduced sedative effects. Examples of non-sedating antihistamines include cetirizine, levocetirizine, loratadine, desloratadine, fexofenadine, and rupatadine. These medications are commonly used to treat allergic rhinitis, urticaria, and angioedema.
Skin tests are medical diagnostic procedures that involve the application of a small amount of a substance to the skin, usually through a scratch, prick, or injection, to determine if the body has an allergic reaction to it. The most common type of skin test is the patch test, which involves applying a patch containing a small amount of the suspected allergen to the skin and observing the area for signs of a reaction, such as redness, swelling, or itching, over a period of several days. Another type of skin test is the intradermal test, in which a small amount of the substance is injected just beneath the surface of the skin. Skin tests are used to help diagnose allergies, including those to pollen, mold, pets, and foods, as well as to identify sensitivities to medications, chemicals, and other substances.
Histamine H1 antagonists, also known as H1 blockers or antihistamines, are a class of medications that work by blocking the action of histamine at the H1 receptor. Histamine is a chemical mediator released by mast cells and basophils in response to an allergic reaction or injury. It causes various symptoms such as itching, sneezing, runny nose, and wheal and flare reactions (hives).
H1 antagonists prevent the binding of histamine to its receptor, thereby alleviating these symptoms. They are commonly used to treat allergic conditions such as hay fever, hives, and eczema, as well as motion sickness and insomnia. Examples of H1 antagonists include diphenhydramine (Benadryl), loratadine (Claritin), cetirizine (Zyrtec), and doxylamine (Unisom).
Drug hypersensitivity is an abnormal immune response to a medication or its metabolites. It is a type of adverse drug reaction that occurs in susceptible individuals, characterized by the activation of the immune system leading to inflammation and tissue damage. This reaction can range from mild symptoms such as skin rashes, hives, and itching to more severe reactions like anaphylaxis, which can be life-threatening.
Drug hypersensitivity reactions can be classified into two main types: immediate (or IgE-mediated) and delayed (or non-IgE-mediated). Immediate reactions occur within minutes to a few hours after taking the medication and are mediated by the release of histamine and other inflammatory mediators from mast cells and basophils. Delayed reactions, on the other hand, can take several days to develop and are caused by T-cell activation and subsequent cytokine release.
Common drugs that can cause hypersensitivity reactions include antibiotics (such as penicillins and sulfonamides), nonsteroidal anti-inflammatory drugs (NSAIDs), monoclonal antibodies, and chemotherapeutic agents. It is important to note that previous exposure to a medication does not always guarantee the development of hypersensitivity reactions, as they can also occur after the first administration in some cases.
The diagnosis of drug hypersensitivity involves a thorough medical history, physical examination, and sometimes skin or laboratory tests. Treatment typically includes avoiding the offending medication and managing symptoms with antihistamines, corticosteroids, or other medications as needed. In severe cases, emergency medical care may be required to treat anaphylaxis or other life-threatening reactions.
A chronic disease is a long-term medical condition that often progresses slowly over a period of years and requires ongoing management and care. These diseases are typically not fully curable, but symptoms can be managed to improve quality of life. Common chronic diseases include heart disease, stroke, cancer, diabetes, arthritis, and COPD (chronic obstructive pulmonary disease). They are often associated with advanced age, although they can also affect children and younger adults. Chronic diseases can have significant impacts on individuals' physical, emotional, and social well-being, as well as on healthcare systems and society at large.
Anaphylaxis is a severe, life-threatening systemic allergic reaction that occurs suddenly after exposure to an allergen (a substance that triggers an allergic reaction) to which the person has previously been sensitized. The symptoms of anaphylaxis include rapid onset of symptoms such as itching, hives, swelling of the throat and tongue, difficulty breathing, wheezing, cough, chest tightness, rapid heartbeat, hypotension (low blood pressure), shock, and in severe cases, loss of consciousness and death. Anaphylaxis is a medical emergency that requires immediate treatment with epinephrine (adrenaline) and other supportive measures to stabilize the patient's condition.
Histamine antagonists, also known as histamine blockers or H1-blockers, are a class of medications that work by blocking the action of histamine, a substance in the body that is released during an allergic reaction. Histamine causes many of the symptoms of an allergic response, such as itching, sneezing, runny nose, and hives. By blocking the effects of histamine, these medications can help to relieve or prevent allergy symptoms.
Histamine antagonists are often used to treat conditions such as hay fever, hives, and other allergic reactions. They may also be used to treat stomach ulcers caused by excessive production of stomach acid. Some examples of histamine antagonists include diphenhydramine (Benadryl), loratadine (Claritin), and famotidine (Pepcid).
It's important to note that while histamine antagonists can be effective at relieving allergy symptoms, they do not cure allergies or prevent the release of histamine. They simply block its effects. It's also worth noting that these medications can have side effects, such as drowsiness, dry mouth, and dizziness, so it's important to follow your healthcare provider's instructions carefully when taking them.
Anti-allergic agents, also known as antihistamines, are a class of medications used to treat allergies. They work by blocking the action of histamine, a substance in the body that is released during an allergic reaction and causes symptoms such as itching, sneezing, runny nose, and watery eyes.
There are two main types of antihistamines: first-generation and second-generation. First-generation antihistamines, such as diphenhydramine (Benadryl) and chlorpheniramine (Chlor-Trimeton), can cause drowsiness and other side effects, such as dry mouth and blurred vision. They are typically used for the treatment of short-term symptoms, such as those caused by seasonal allergies or a mild reaction to an insect bite.
Second-generation antihistamines, such as loratadine (Claritin) and cetirizine (Zyrtec), are less likely to cause drowsiness and other side effects. They are often used for the long-term treatment of chronic allergies, such as those caused by dust mites or pet dander.
In addition to their use in treating allergies, antihistamines may also be used to treat symptoms of motion sickness, insomnia, and anxiety. It is important to follow the instructions on the label when taking antihistamines and to talk to a healthcare provider if you have any questions or concerns about using these medications.
Food hypersensitivity is an umbrella term that encompasses both immunologic and non-immunologic adverse reactions to food. It is also known as "food allergy" or "food intolerance." Food hypersensitivity occurs when the body's immune system or digestive system reacts negatively to a particular food or food component.
Immunologic food hypersensitivity, commonly referred to as a food allergy, involves an immune response mediated by immunoglobulin E (IgE) antibodies. Upon ingestion of the offending food, IgE antibodies bind to the food antigens and trigger the release of histamine and other chemical mediators from mast cells and basophils, leading to symptoms such as hives, swelling, itching, difficulty breathing, or anaphylaxis.
Non-immunologic food hypersensitivity, on the other hand, does not involve the immune system. Instead, it is caused by various mechanisms, including enzyme deficiencies, pharmacological reactions, and metabolic disorders. Examples of non-immunologic food hypersensitivities include lactose intolerance, gluten sensitivity, and histamine intolerance.
It's important to note that the term "food hypersensitivity" is often used interchangeably with "food allergy," but it has a broader definition that includes both immunologic and non-immunologic reactions.
Cetirizine is an antihistamine medication that is used to relieve symptoms of allergies, such as hay fever, hives, and other allergic skin conditions. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Cetirizine is available over-the-counter and by prescription in various forms, including tablets, chewable tablets, and syrup.
The medical definition of Cetirizine is:
Cetirizine hydrochloride: A second-generation antihistamine with selective peripheral H1 receptor antagonist activity. A potent and long-acting inhibitor of the early and late phases of the allergic reaction, it exhibits anti-inflammatory properties and has a more favorable side effect profile than many other antihistamines. It is used in the management of allergic rhinitis, chronic urticaria, and angioedema.
Immunoglobulin E (IgE) is a type of antibody that plays a key role in the immune response to parasitic infections and allergies. It is produced by B cells in response to stimulation by antigens, such as pollen, pet dander, or certain foods. Once produced, IgE binds to receptors on the surface of mast cells and basophils, which are immune cells found in tissues and blood respectively. When an individual with IgE antibodies encounters the allergen again, the cross-linking of IgE molecules bound to the FcεRI receptor triggers the release of mediators such as histamine, leukotrienes, prostaglandins, and various cytokines from these cells. These mediators cause the symptoms of an allergic reaction, such as itching, swelling, and redness. IgE also plays a role in protecting against certain parasitic infections by activating eosinophils, which can kill the parasites.
In summary, Immunoglobulin E (IgE) is a type of antibody that plays a crucial role in the immune response to allergens and parasitic infections, it binds to receptors on the surface of mast cells and basophils, when an individual with IgE antibodies encounters the allergen again, it triggers the release of mediators from these cells causing the symptoms of an allergic reaction.
Loratadine is an antihistamine medication that is commonly used to relieve symptoms of allergies, such as hay fever, hives, and other skin reactions. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Loratadine is available over-the-counter in various forms, including tablets, capsules, and syrup.
The medical definition of loratadine is: "A second-generation antihistamine used for the symptomatic treatment of allergies, including hay fever, hives, and other skin reactions. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms."
It's important to note that while loratadine is generally considered safe, it can cause side effects such as dizziness, dry mouth, and headache. If you have any concerns about taking loratadine or experience severe side effects, you should speak with your healthcare provider.
Anisakiasis is a gastrointestinal disease caused by the accidental consumption and infection with larvae of nematode parasites belonging to the genus Anisakis. The life cycle of these parasites typically involves marine animals such as fish and squid, which serve as intermediate or paratenic hosts. Human infections usually occur when people eat raw or undercooked seafood that contains infective larvae.
After ingestion, the larvae can penetrate the gastrointestinal mucosa, causing an inflammatory reaction and potentially leading to symptoms such as abdominal pain, nausea, vomiting, diarrhea, or fever. In some cases, the larvae may invade deeper tissues, resulting in more severe complications like allergic reactions, intestinal obstruction, or perforation.
Diagnosis of anisakiasis is often based on clinical presentation, epidemiological data, and detection of parasite larvae in biopsy samples, stool specimens, or vomitus. Treatment typically involves endoscopic removal of the larvae, supportive care for symptoms, and sometimes anti-parasitic medication. Preventive measures include thoroughly cooking seafood, freezing it at temperatures below -20°C (-4°F) for at least 7 days, or practicing proper hygiene during food preparation to minimize the risk of infection.
"Cold temperature" is a relative term and its definition can vary depending on the context. In general, it refers to temperatures that are lower than those normally experienced or preferred by humans and other warm-blooded animals. In a medical context, cold temperature is often defined as an environmental temperature that is below 16°C (60.8°F).
Exposure to cold temperatures can have various physiological effects on the human body, such as vasoconstriction of blood vessels near the skin surface, increased heart rate and metabolic rate, and shivering, which helps to generate heat and maintain body temperature. Prolonged exposure to extreme cold temperatures can lead to hypothermia, a potentially life-threatening condition characterized by a drop in core body temperature below 35°C (95°F).
It's worth noting that some people may have different sensitivities to cold temperatures due to factors such as age, health status, and certain medical conditions. For example, older adults, young children, and individuals with circulatory or neurological disorders may be more susceptible to the effects of cold temperatures.
Cyproheptadine is an antihistamine and anticholinergic medication that is primarily used to treat symptoms of allergies, such as runny nose, sneezing, and itching. It works by blocking the action of histamine, a substance in the body that causes allergic reactions.
Cyproheptadine also has other uses, including the treatment of migraines and cluster headaches, appetite stimulation in people with certain medical conditions, and as a sedative in some cases. It is available in various forms, such as tablets, capsules, and syrup.
Like all medications, cyproheptadine can have side effects, including drowsiness, dry mouth, dizziness, and blurred vision. It is important to follow the dosage instructions carefully and talk to a healthcare provider if you experience any bothersome or persistent side effects.
